Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492610, here are decompositions:

7 + 31492603 = 31492610
13 + 31492597 = 31492610
43 + 31492567 = 31492610
73 + 31492537 = 31492610
139 + 31492471 = 31492610
157 + 31492453 = 31492610
181 + 31492429 = 31492610
211 + 31492399 = 31492610

Showing the first eight; more decompositions exist.
